Climate Change and Global Warming

            
             Global warming and climate change refer to an increase in average global temperatures. Natural events and human activities are believed to be contributing to an increase in average global temperatures. This is caused primarily by increases in "greenhouse " gases such as Carbon Dioxide (CO2). A warming planet thus leads to a change in climate which can affect weather in various ways, as discussed further below.
             2. What Are Global Warming And Climate Change?.
             2.1 What Is Climate Change?.
             Climate change is one of the biggest issues facing the world today.  Climate change refers to a change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods.
             2.2 What Is Global Warming?.
             Global warming is the increased heat trapped in the earth's atmosphere resulting from excess greenhouse gases such as Carbon Dioxide (CO2). These naturally occurring gases including Methane (CH4)  & Nitrous Oxide (N20) form a layer in the atmosphere reflecting the sun's rays back down to the earth. These gases are exacerbated in the atmosphere by fossil fuel use for energy (i.e. coal and oil) and the alteration to our natural landscape. This has an unnatural warming effect on our fragile environment. .
             2.3 What Is The Greenhouse Effect?.
             Greenhouse effect is the process where energy from the sun drives the earth's weather and climate, and heats the earth's surface. In turn, the earth radiates energy back into space and some atmospheric gases (water vapour, carbon dioxide, and other gases) trap some of the outgoing energy, retaining heat somewhat like the glass panels of a greenhouse. These gases are therefore known as greenhouse gases. The greenhouse effect is the rise in temperature on Earth as certain gases in the atmosphere trap energy.

Essays Related to Climate Change and Global Warming

1. The Time Scale of Global Warming

Elizabeth Kolbert once said, "Global warming is all about scale" While it would be ideal to solve today's rising climate change problems expediently, there are many factors in society that instead prevent us from implementing positive solutions in the environment. When you look at climate change on a global or geographic scale, it is difficult to pinpoint one country, region, continent, or even hemisphere as the main source of conflict. Collectively, our global society has contributed to global warming, each in our own rights. ... Consequently, global warming is not seen as a ...

2. Climate Change and Global Warming

Science has repeatedly proven the existence of global warming, however the battle to convince the public is no longer scientific. Due to the political activism of Republicans attempting to exploit false ideology or feign ignorance over the presence of climate change, it is impossible to convince the global population of the imminent threat. ... In 1957, renowned oceanographer Robert Revelle was among those to first study global warming. ... In November 1956, he compiled a report from scientists, physicians, and engineers about the presence of global warming. ... Although Johnson had suggest...

In fact, the Intergovernmental Panel on Climate Change, the world's authority on climate change, predicts that the 21st Century will see a warming much more drastic than that seen during the 20th Century. ... Anthropogenic causes of global climate change are not limited to changes in the levels of greenhouse gasses in the atmosphere. ... Therefore, it would overestimate global warming. ... There are many natural forcing events that occur often, producing much of the change in global climate. ...

4. Global Warming

GLOBAL WARMING In 1990, the Intergovernmental Panel on Climate Change (IPCC), an international body established by the United Nations to provide scientific advise to global policy makers regarding such issues as the buildup of greenhouse gases, evidence and attribution of climate change, and predictions of global climate scenarios over the next century, issued its inagural report. ... For example, according to the IPCC's 1990 climate model, increased global surface temperatures resulting from the greenhouse effect of higher CO2 atmospheric concentrations "force- other climate ch...

5. The Enviroment and Global Climate Change

The most pressing ecological issue of our time, in my opinion is the global climate change. ... There are many striking evident reactions to the global climate change. ... The most apparent cause of the global climate change is because of greenhouse gases or the "green house effect". ... The global climate change is the top ecological issue that our planet faces today. There are so many factors which come in play when global climate change is discussed because of the many causes,effects, and the strong evidence that it is present. ...

6. Global implications of climate change

Global Warming - Its Implications on the Human Population Though there is some scepticism that climate change is a result of human actions, it is unlikely to be a natural event. Some dismiss the phenomenon known as "global warming" as a hoax, and claim that yuppies driving SUVs could not possibly change the overall temperature of the earth. In a sense, this misguided notion is true- but climate change is much more than "yuppies driving SUVs." ... Climate change would change our ecology with respect to biodiversity, nutrient cycle, physical relocation, internal defence systems, and transmi...

A Global Problem: Responsibility for Climate Change. ... Taking unified global action against climate change, however, has proven contentious. ... Continued warming would also lead to shifts in rainfall patterns as global precipitation increases. ... Future emissions profiles will determine the end extent of global climate change. ... Global Political processes: The international community began attempts to address climate change in 1992 with the adoption of the United Nations Framework Convention on Climate Change (UNFCCC). ...
